Jeff Chen notes: Another highly polished piece of work from one of the masters. Five theme answers, all common three-word admonitions with IT in the middle, interpreted in wacky ways. It's especially nice that they're all clued as "That's enough!" to a specific type of person. My favorite was KEEP IT DOWN to a hot-dog eating contestants, as it hits on my fascination with competitive eating. There's a sport-specific term called a "reversal" which I won't go into.

Where Ian really makes a name for himself as a constructor is his ability to jam-pack snazzy fill into a puzzle with clean overall results. With five medium-length themers, many constructors would call it good to have simply one pair of long downs. Ian's moved way past that point, giving us GAS STOVE, SEES FIT, CREW TEAM with its fun clue, APE SUIT. And that's just in two of the corners!

Because the central entry is an "inconvenient length" (it sort of splits the grid into an upper and a lower half), it forces open white spaces in the NE and SW. As anyone who's tried to fill a moderate-size chunk of crossword grid knows, it's not easy to do with quality. Sure, it's a simple thing to fill a subsection so that it works, but it's another matter completely to do it without a single blemish. With only a single glue-y answer (CHA) to hold it all together, Ian still manages to work in EXACTA, TEN HUT, ECOLAW. Ian even rescues CHA with a really fun clue.

How does he do it, you might ask? Some people assume that constructors just hit a button and let the computer do the work for them. Some constructors actually do that, but the auto-fill process almost always spits out subpar fill. I've had the pleasure of working with Ian on a few grids, so I've seen that he takes a significant amount of time with every grid he makes, trying out multiple layouts, testing out dozens of possibilities in the critical junctions to figure out what will help him fill cleanly. From there, it's a matter of trial and error guided by hundreds of puzzles worth of grid-building experience to produce a clean result.

What's most impressive is Ian's track record of consistency. Whenever I see his name on a byline, I know I'm going to get a fun theme with more than a handful of long fill and a minimum of cruddy answers. This puzzle is no different, especially difficult given that the best Tuesday puzzles are smooth enough for relative beginners but interesting enough for more experienced solvers. I tip my hat to you, sir!
